Abstract (en)

[origin: WO2021119673A1] Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a radio frequency (RF) receiver including a dual-mode low noise amplifier (LNA). One of the methods includes configuring the RF receiver to a wideband mode including operation over a multiple receive frequency (RX) bands including multiple frequencies, receiving, by the RF receiver, an input RF signal, scanning the multiple frequencies to detect a transmitted frequency of the input RF signal, configuring the RF receiver to narrowband mode including operation over a proper subset of the RX bands including a proper subset of the multiple frequencies, and tuning the RF receiver to the transmitted frequency.
